Cheap and simple evaluation board for the STM32F042G6Ux microcontroller, with direct USB connectivity.
This project involved the end-to-end design and development of a compact, low-power IoT system using the ESP32-C3-02 SoC and integrated TP4056 Li-ion battery charger. The goal was to create a reliable and modular platform for wireless environmental data monitoring, powered by a rechargeable battery with onboard protection and USB-C support.
Open source digital servo replacement module for the Sony Walkman WM-D6C. Replaces the CX20084 servo IC, CP304 boost converter, and CN301 power jack with a single STM32G0B1-based PCB. Dual variant: USB-C PD or polarity-agnostic barrel jack input. Bare-metal C firmware. CERN OHL-P v2 / MIT / CC BY 4.0.
